Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gate-controlled technology is implemented in traditional X-ray machines, then imaging quality is improved and radiation damage is reduced, but device volume and structural complexity increase significantly
Solution Approach 1:
The patent integrates the high-voltage generating apparatus and gate-controlled voltage unit into a single sealed container filled with transformer oil, eliminating the need for separate isolation transformers and high-voltage cables. This merging of previously separate components resolves the contradiction by achieving gate-controlled functionality (improved imaging quality and reduced radiation damage) while dramatically reducing device volume for portable application
Solution Approach 2:
The sealed container serves multiple functions simultaneously: it provides electrical insulation, houses the high-voltage generating apparatus, contains the gate-controlled voltage unit, and eliminates the need for external isolation transformers. This multi-functionality resolves the contradiction by integrating gate-controlled technology into a compact form factor suitable for portable devices
2Reliability
If multiple isolation transformers are used in gate-controlled X-ray machines, then electrical isolation is achieved, but device complexity and volume increase
Solution Approach 1:
The patent extracts and eliminates the need for multiple external isolation transformers by integrating the gate-controlled voltage unit directly into the high-voltage generating apparatus. The transformer oil-filled sealed container provides the necessary electrical isolation internally, resolving the contradiction by maintaining reliability through isolation while dramatically reducing structural complexity
Solution Approach 2:
The transformer oil serves as an intermediary medium that provides electrical insulation and isolation between the high-voltage generating apparatus and gate-controlled voltage unit within the sealed container. This intermediary approach resolves the contradiction by achieving the necessary electrical isolation without requiring multiple discrete isolation transformers
